PostFix is a high-performance, two-part polyurethane expanding foam designed for the rapid installation of non-structural posts. This lightweight, mix-in-the-bag solution eliminates the need for heavy concrete bags, water, or specialized tools, setting in as little as three minutes. It provides a high-strength, water-resistant backfill that seals and protects the base of wooden, PVC, and steel posts against moisture and decay. Ideal for fence posts, mailboxes, and signage, it offers a convenient and efficient alternative for professional contractors and large-scale building projects.

Sika PostFix is a two-part, pre-proportioned polyurethane resin which when mixed produces an expanding foam. It has been specifically formulated and packaged to provide a lightweight, mix-in-the-bag, fast-setting and high-strength backfill for wooden, PVC and steel in ground supports. Sika® PostFix is based upon Sika's proven foam technology and designed for easy, convenient and quick support of many types of posts.

General Ledger Coding

General Ledger Coding is a value added service provided for you at no additional cost.

General Ledger Coding makes accounting easier by providing you with a calculated total of purchases based on your General Ledger Codes.

In addition to traditional General Ledger Summary provided at time of invoice, we can also provide quotes and order acknowledgements with General Ledger Coding as well. We also give you the ability to change a GL Code for one or all items for renovation projects that may utilize a single GL Code. We can also code any of our "extended inventory" items with your General Ledger Code at the time of quote, order confirmation and invoicing as well. We can code our item numbers directly to your GL Codes should our item categories not align directly with your GL Code Categories.

Please contact us if you wish to implement our General Ledger Coding feature.

Any and all prices are subject to change without notice. We will always bill you at current prices prevailing at the time of shipment (excluding backorders). Availability of product can change at any time. We receive products daily and the availability may not always reflect what is in stock.
